Description

Control method, device and system for multi-carrier high-speed uplink packet access transmission

The present invention relates to the field of wireless communications, and in particular, to a method, an apparatus, and a system for controlling a multi-carrier high-speed uplink packet access (HSUPA) transmission mode.

Background technique

UMTS (Universal Mobile Telecommunications System) is a third-generation mobile communication system using WCDMA (Wideband Code Division Multiple Access) air interface technology. The UMTS system is generally called a WCDMA communication system.

The 3GPP (3rd Generation Partnership Project) has passed the HSPA (High Speed Packet Access) evolution research project. For WCDMA mobile stations, the challenge is still the need for continuous reception and transmission, which requires the RF component to operate full time during voice and data calls. Release 7 version of 3GPP for HSDPA

(High Speed Downlink Packet Access) /HSUPA (High Speed Uplink Packet Access) introduces DTX (Discontinuous Transmission) / DRX (Discontinuous Reception) scheme. It helps to reduce the power consumption of burst data services and low-speed packet data services such as VoIP, or IP-based voice services.

In the Release 6 version, the physical control channel is transmitted in the uplink direction even if there is no data channel activation, and it is improved in Release 7. When there is no user plane data to be transmitted, the UE

(User Equipment, User Equipment) will cut off the transmission of the control channel. This scheme is called discontinuous transmission of the uplink, or more accurately, it is called the uplink DPCCH (Dedicated Physical Control Channel). Discontinuous transmission, which allows the radio part of the terminal to be cut off when there is no content transmission. If you set the UE's DTX and DRX are activated variables

When (UE_DTX_DRX_Enabled) is set to true (TRUE), the uplink DPCCH discontinuous transmission is activated, and may also be activated or deactivated by downlink shared control channel signaling (HS-SCCH order). This mechanism allows uplink DPCCH transmissions to be adaptive to upstream data transmission.

The uplink DPCCH defines two DTX periods: the set value UE_DTX_cycle-1 and another set value UE_DTX_cycle-2. Wherein, UE_DTX_cycle-1 indicates the length of time of a certain predetermined number of subframes, and UE_DTX_cycle-2 indicates the length of time of another predetermined value of subframes, and others are similar. And usually UE_DTX_cycle-1 "UE-DTX-cycle-2". For example, a certain radio frame starts to perform DTX of the uplink DPCCH at a periodic interval of UE_DTX_cycle-1, and if there is an E-DCH (Enhanced Dedicated Channel) transmission in UE_DTX_cycle_1, UE_DTX is maintained. – cycle-1 is the DTX of the upstream DPCCH for the periodic interval. During the DTX of the uplink DPCCH in the period of UE_DTX_cycle-1, if there is no E-DCH transmission within a set time window, the uplink DPCCH performs DTX with a period of UE_DTX_cycle-2, The set time window is Inactivity - Threshold - for - UE - DTX - cycle - 2. Upstream DPCCH During DTX, if there is a channel transmission other than DPCCH in a certain time slot, the DPCCH needs to be sent in this time slot.

In order to meet the growing demand of wireless services, a multi-carrier WCDMA communication system is proposed based on the existing single-carrier WCDMA communication system. Starting from R9, the WCDMA system introduces dual-carrier simultaneous operation to the uplink, further increasing the uplink data transmission rate. In the case of multiple carriers, the base station selects a better carrier for scheduling (this carrier is called a scheduling carrier) to obtain throughput gain. At this time, it is necessary to set the transmission mode of the dataless carrier (or non-scheduled carrier). .

detailed description

The method, device and system for controlling the transmission mode of the multi-carrier HSUPA according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

It should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of them. Example. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

An embodiment of the present invention provides a method for controlling a multi-carrier HSUPA transmission mode, including: transmitting downlink control signaling to a UE, where the downlink control signaling is used to indicate a DPCCH burst of an uplink non-scheduled carrier of the UE by UE-DTX - cycle - 2 is a discontinuous transmission of a period or a discontinuous transmission of a period at a predetermined time interval; wherein the predetermined time interval > UE - DTX - cycle - 2.

In this embodiment, after receiving the downlink control signaling, the UE can control the DPCCH burst of the non-scheduled subcarrier according to the signaling to perform discontinuous transmission in the period specified in the control signaling, and can send the uplink carrier. The mode is set to achieve the purpose of controlling the transmission mode of the unscheduled carrier.

As shown in FIG. 1, another embodiment of the present invention provides a method for controlling a transmission mode of a multi-carrier HSUPA, including:

S101. The downlink control signaling sent by the network side is received, where the downlink control signaling is used to indicate that the DPCCH burst of the uplink non-scheduled carrier of the UE is discontinuously transmitted in a period of UE_DTX_cycle-2 or at a predetermined time. The interval is a periodic discontinuous transmission; wherein, the predetermined time interval > UE - DTX - cycle - 2;

5102. Control, according to the received downlink control signaling, a DPCCH burst of the uplink non-scheduled carrier to be discontinuously transmitted in a period of UE_DTX_cycle-2 or discontinuously transmitted in a periodic time interval.

On the basis of the foregoing solution, the method further includes: setting a scheduling frequency according to a multi-carrier HSUPA (High Speed Uplink Packet Access) and/or a UE-DTX-cycle-2 The length of time of the predetermined time interval is such that the non-scheduled carrier can operate stably in multi-carrier scheduling.

In the prior art, only when there is no E-DCH transmission on the uplink carrier in the time window Inactivity_Threshold_for_UE_DTX_cycle-2, the carrier can enter the DPCCH burst with the UE-DTX-cycle-2 cycle. In the state where the above conditions are not met, the carrier cannot enter the state in which the DPCCH burst is transmitted in the period of UE_DTX_cycle-2. Therefore, an embodiment of the present invention The method for controlling the transmission mode of the multi-carrier HSUPA, by transmitting downlink control signaling to the UE by the network side, in which the DPCCH burst of the non-scheduled carrier on the UE is specified in the UE-DTX-cycle-2 as a discontinuity After receiving the signaling, the UE can learn, according to the signaling, that the DPCCH burst of the non-scheduled carrier should be discontinuously transmitted in the period of UE_DTX_cycle-2, so that after receiving the carrier switching command subsequently, The non-scheduled carrier can be quickly controlled to enter a state in which discontinuous transmission is performed in a period of UE-DTX_cycle-2.

In addition, the method for controlling the transmission mode of the multi-carrier HSUPA in the embodiment of the present invention may further, by the network side, transmitting downlink control signaling to the UE, where the DPCCH burst of the non-scheduled carrier on the UE is specified in the signaling for a predetermined time. The interval is discontinuously transmitted for a period, and the predetermined time interval is > UE-DTX_cycle-2. Therefore, the power consumption of the UE on the non-scheduled carrier can be reduced, and the system throughput can be improved.

The application embodiment of the present invention will be described more specifically below by applying the scheme of the present invention to carrier switching of a multi-carrier HSUPA. The transmission mode of the non-scheduled carrier in the following embodiments may include: a first transmission mode, a second transmission mode, or a third transmission mode.

The first transmission mode is a DTX mode of the existing DPCCH. The first transmission mode specifically comprises: when the start-carriers UE-DTX- cycle- 1 discontinuous transmission cycle of uplink DPCCH burst ₀ if E-DCH transmission within 1 UE-DTX- cycle-, is held in a UE-DTX- Cycle-1 is a discontinuous transmission of DPCCH burst for a period; if there is no E-DCH transmission within a set time window, the DPCCH burst is discontinuously transmitted with a period of UE_DTX_cycle-2, and the set time window is Inactivity - Threshold - for - UE - DTX - cycle - 2.

The DPCCH burst in which the second transmission mode is a carrier is transmitted at a second predetermined time interval, that is, the above-mentioned UE-DTX_cycle-2.

The DPCCH burst in which the third transmission mode is a carrier is transmitted at a third predetermined time interval greater than the second predetermined time. In this embodiment, the third predetermined time interval is referred to as UE-DTX_cycle-3.

As shown in FIG. 2, it is a flowchart of a control method of a transmission mode of a multi-carrier HSUPA according to an application embodiment of the present invention. The method of this embodiment may include the following steps:

S201. The base station sends downlink control signaling to the UE, where the signaling indicates that the UE is not scheduled by the uplink. The transmission mode in which the carrier enters.

For example, the base station may indicate that the uplink non-scheduled carrier of the UE enters the first transmission mode, the second transmission mode, or the third transmission mode. After receiving the signaling, the UE learns the mode that the non-scheduled carrier should enter after the carrier switching.

S202: The base station sends an E-AGCH (E-DCH Absolute Grant Channel) signaling to the UE, where the signaling indicates which carrier is the scheduled carrier and which carrier is the non-scheduled carrier.

Of course, for other embodiments of the present invention, other downlink control signaling may also be used to notify the UE which carriers are scheduled carriers and which carriers are non-scheduled carriers. For example, the HS-SCCH order (Shared Control Channel for High Speed-Downlink Shared Channel order) may be used to notify the UE which carriers are scheduled carriers and which carriers are non-scheduled carriers.

Since the E-AGCH signaling is used to indicate which carrier is the scheduled carrier and which carrier is the non-scheduled carrier, the signaling can achieve the purpose of carrier switching.

S203. The UE controls the non-scheduled carrier to enter the transmission mode specified in S201 according to the received E-AGCH signaling. Since the non-scheduled carrier enters the transmission mode specified in S201, the unscheduled carrier and the scheduling carrier can be in different transmission modes.

Therefore, in the method for controlling the transmission mode of the multi-carrier HSUPA, the network-side device sends downlink control signaling to the UE, and the uplink non-scheduled carrier of the UE is designated to enter the first transmission mode and the second transmission in the signaling. In the mode or the third transmission mode, after receiving the signaling, the UE can control the non-scheduled carrier to enter the specified transmission mode according to the signaling, and can implement a mode for controlling the non-scheduled carrier to enter a small power consumption, thereby reducing the UE in the mode. Power consumption on non-scheduled carriers increases system throughput.

For the embodiment of the present invention, in addition to being able to control the non-scheduled carrier to enter the specified transmission mode when the two carriers are switched, the UE can also control the non-scheduled carrier to enter the corresponding manner for the handover condition of more than two carriers. The sending mode.

The following will be described in conjunction with the application embodiment shown in FIG. 2 in various scenarios. In Figure 3 ~ Figure 6, Taking 2ms E-DCH TTI (Transmit Time Interval) as an example, the timing start point is 0, and CFN is the Connection Frame Number. The subframes identified in FIG. 3 to FIG. 6 are 2 ms E-DPDCH (E-DCH Dedicated Physical Data Channel) / E-DPCCH subframe, and the radio frame is 10 ms E-DPDCH/ E-DPCCH radio frame.

scene one

As shown in FIG. 3, in the initial state, the UE uplink carrier is carrier 1 and carrier 2. In the initial state, both uplink carrier 1 and carrier 2 transmit data. In Figure 3, carrier 1 carrier 2 is assumed to be the first transmission mode, that is, the existing DTX transmission mode. The uplink DPCCH burst of carrier 1 and carrier 2 is transmitted in the period of 0 to 10 ms in the period of UE_DTX_cycle-1. It should be noted that the initial state of carrier 1 carrier 2 can also be the DPCCH continuous transmission mode.

It can be seen that in Figure 3, at 0 ~ 2ms, a DPCCH burst is sent on carrier 1, and a DPCCH burst is also sent on carrier 3. These are the upstream frames sent in the initial state.

In conjunction with the embodiment shown in FIG. 2, the base station indicates that the non-scheduled carrier on the UE enters the third transmission mode by using downlink control signaling sent to the UE. After receiving the signaling, the UE learns the mode that the non-scheduled carrier should enter after the carrier switching.

Then, the base station sends an E-AGCH (E-DCH Absolute Grant Channel) signaling to the UE, where the signaling indicates that the UE carrier 2 is a scheduling carrier, and the carrier 1 is a non-scheduled carrier. As shown in Figure 3, the UE receives E-AGCH signaling between 10 and 12 ms.

The E-AGCH signaling may be combined with the foregoing signaling indicating that the non-scheduled carrier enters the third transmission mode: when there is data transmission on the carrier 2, the original transmission mode is maintained; and no data is transmitted on the carrier 1 to enter the third transmission. mode.

After receiving the E-AGCH signaling, the UE controls the carrier 1 to enter the third transmission mode after 12 ms. 1 is no longer transmitting data on a carrier, the third transmission mode, i.e. UE-DTX- cycle- time interval 3 transmits DPCCH burst ₀ to 3, on a DPCCH burst is 8 - transmission time of 10ms, Since the third transmission mode is entered, the next DPCCH burst is transmitted after the time interval of UE_DTX_cycle-3, that is, 32 to 34 ms.

The carrier 2 is a scheduling carrier, and the UE maintains the transmission mode of the carrier as the first transmission mode. In There When data is transmitted, the uplink DPCCH burst is sent in the period of UE-DTX_cycle-1. If there is no E-DCH transmission in the Inactivity-Threshold-for-UE-DTX-cycle-2 subframes, the uplink DPCCH burst is UE- DTX—cycle—2 is a periodic transmission.

Moreover, in the subsequent situation, if the base station makes different handover decisions according to the carrier condition, for example, if carrier 1 is desired as the scheduling carrier and carrier 2 is the non-scheduled carrier, then the E-AGCH signaling or other downlink information can still be used. Let the UE be notified to re-control the transmission mode of each carrier.

Scene two

As shown in FIG. 4, the uplink carrier 1 and the carrier 2 of the UE transmit data in the initial state. It is assumed that carrier 1 is in the continuous DPCCH transmission mode, carrier 2 is in the first transmission mode, and the uplink DPCCH burst of carrier 2 is transmitted in the period of UE_DTX_cycle-1 between 0 and 10 ms. . The base station indicates the UE by using downlink control signaling, and the non-scheduled carrier enters the third transmission mode.

Afterwards, the base station notifies the UE through E-AGCH signaling that carrier 1 is a non-scheduled carrier and carrier 2 is a scheduling carrier. For this signaling, refer to the E-AHCH signaling received by the UE between 10 and 12 ms in Figure 4. After receiving the E-AGCH signaling, the UE controls the carrier 1 to enter the third transmission mode after 12 ms. Therefore, no data is transmitted on carrier 1, and the DPCCH burst is transmitted in the third transmission mode, that is, at the time interval of UE_DTX_cycle-3. As shown in FIG. 3, since the third transmission mode is entered, the next DPCCH burst is transmitted after the time interval of UE_DTX_cycle-3, that is, 34 to 36 ms.

Similarly, in this scenario, the transmission mode of the unscheduled carrier can be controlled to implement carrier switching quickly.

Scene three

As shown in FIG. 5, in the initial state, the UE uplink carrier is carrier 1 and carrier 2, and uplink carrier 1 and carrier 2 both transmit data. FIG. 5 assumes that carrier 1 is a continuous DPCCH transmission mode; carrier 2 is a first transmission mode. And the uplink DPCCH burst of carrier 2 is transmitted in the period of UE_DTX_cycle-1 between 0 and 10 ms.

In this scenario, the base station informs the UE that the non-scheduled carrier enters the second transmission mode by using downlink control signaling, that is, sends the DPCCH burst at a time interval of UE_DTX_cycle-2. The base station makes a decision according to each carrier condition, and informs the UE that carrier 1 is a non-scheduled carrier by E-AGCH signaling, and carrier 2 is a scheduling carrier. For the signaling, reference may be made to the E-AGCH signaling received by the UE between 10 and 12 ms in FIG.

After receiving the E-AGCH signaling, the UE controls the carrier 1 to enter the second transmission mode, that is, the DPCCH burst is sent at a time interval of UE_DTX_cycle-2.

For carrier 2, the UE does not control and maintains the original first transmission mode. In FIG. 5, after receiving the E-AGCH signaling, the UE sends the DPCCH at the time interval of UE_DTX_cycle-1 for the time indicated in the figure. Burst, and triggers the transmission of the DPCCH burst in the subframe with E-DCH transmission.

Scene four

As shown in FIG. 6, in the initial state, the UE uplink carrier is carrier 1 and carrier 2, and both uplink carrier 1 and carrier 2 transmit data, and it is assumed that carrier 1 and carrier 2 are both in the first transmission mode.

First, the base station indicates the UE by using downlink control signaling, and the non-scheduled carrier enters the first transmission mode. The base station makes a decision according to each carrier condition, and informs the UE that the carrier 1 is a non-scheduled carrier and the carrier 2 is a scheduling carrier through E-AGCH signaling. For the signaling, reference may be made to the E-AGCH signaling received by the UE between 10 and 12 ms in FIG.

As can be seen from Fig. 6, after receiving the carrier switching information, since the carrier 1 is originally transmitting the uplink DPCCH in the first transmission mode, it does not need to be changed. Moreover, since carrier 1 is a non-scheduled carrier and there is no uplink E-DCH transmission, after passing In activity_Threshold_for_UE_DTX_cycle-2, it will enter the time interval of sending UE-DTX_cycle-2 The status of the DPCCH burst.

While carrier 2 is the scheduling carrier, the UE does not perform other control, and also maintains the first transmission mode. If there is always E-DCH transmission on carrier 2, then carrier 2 sends DPCCH burst at the time interval of UE-DTX_cycle-1 until the E-DCH is sent to the time window without E-DCH transmission Inactivity_ Threshold_for – After UE-DTX—cycle—2, it is possible to change the time interval for DPCCH burst transmission.

For the MC-HSUPA (Multi-Carrier HSUPA, Multi-Carrier HSUPA) system, The number of users is large, and the system load is heavy, and a UE with multi-load demand can transmit data on multiple carriers at the same time to obtain a larger data rate. In this case, the handover of the multi-carrier HSUPA transmission mode is introduced, which can alleviate the problem of uplink interference and excessive cell load, reduce RoT (Raise Over Thermal), and optimize system performance. Embodiments of the present invention reduce the power consumption of the UE on non-scheduled carriers and increase the throughput of the system.
